Problems with focus and impulse control can be common developmental stages through which children and adolescents naturally progress. But they can also be symptoms of attention-deficit hyperactivity disorder (ADHD), a chronic condition.
ADHD is a pattern of inattention or hyperactivity and impulsivity (or both) that interferes with functioning or development, and persists into adulthood. ADHD affects around 7.6% of children aged three to 12 years and 5.6% of teens.
